It all comes down to the limit of level 9 in mines. Once you hit that 600ql cap on stones from mineable walls the whole world stalls.
Then the bone wall becomes the progress, who can produce the most bone to make bone clay it all.
After that it's the end tree game, getting outside the limitations of the current animal quality caps via domestic animals, domestic string and domestic meat all for mulch, better pot and that slows pretty fast (i blame breeding quality, we just don't need it on animals as they have a softcap via food(or milk) in their belly).
The issue is once the game hits that point it slows down so much that stats/skills can chill and rarely need to grow for more than a few people.
What the game needs is to consider the scaling factor of mine levels and then find a way to recycle and reuse them over time (think terraria but with quality). This would then bring the rest of the game in line except the pve content, that needs to be enhanced via realm buffs (animal buff = harder fight but better ql (new mechanics like swimming animals XD)).
You can honestly change this thread to the game needs endgame content
